Idk. Id rather think these are the ones you want alive and sickly because they're the ones that obey. Maybe kill some off to get pop numbers where you, as a demented evil globalist, want them, but keep the obedient ones. They're profitable and more docile.

What's truly frightening about your theory though, is who they would have in mind to replace our first responders and other "essential" workers. No detail is left unplanned or unexploited.
